We're dividing 13878549 by 436 
Our goal is to divide 13878549 by 436.

Advancing to step 1:
436 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 436

Let's proceed to step 2:
13 divided by 436 is 0 with a remainder of 13.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 13 leaves us with 13.
Fetch the next digit (8) from the dividend, attach it to 13 and continue: 138 / 436

Going ahead to step 3:
The number 436 fits into 138 0 times, leaving a remainder of 138.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 138, we end up with 138.
Include the next digit (7) from the dividend after 138, then repeat: 1387 / 436

Moving on to step 4:
If we divide 1387 by 436, we get 3 and a remainder of 79.
The next digit of our result is 3. 
Result so far: 3.0
The remainder is 79 after subtracting 1308 from 1387.
Append the next digit (8) from the dividend to 79 and continue with: 798 / 436

Step 5:
If we divide 798 by 436, we get 1 and a remainder of 362.
The next digit of our result is 1. 
Result so far: 31.0
If we subtract 436 from 798, we get 362.
Bring next digit (5) of the dividend behind the 362 and repeat the process: 3625 / 436

Let's proceed to step 6:
436 goes into 3625 8 times with a remainder of 137.
Use 8 as the next digit of our solution. 
Result so far: 318.0
If we take 3488 away from 3625, we end up with 137.
Fetch the next digit (4) from the dividend, attach it to 137 and continue: 1374 / 436

Moving on to step 7:
The number 436 fits into 1374 3 times, leaving a remainder of 66.
Use 3 as the next digit of our solution. 
Result so far: 3183.0
Deduct 1308 from 1374 and we're left with 66.
Include the next digit (9) from the dividend after 66, then repeat: 669 / 436

Moving on to step 8:
If we divide 669 by 436, we get 1 and a remainder of 233.
Record the quotient 1 as the next digit in the result. 
Result so far: 31831.0
If we subtract 436 from 669, we get 233.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2330, and continue the process.

Step 9:
If we divide 2330 by 436, we get 5 and a remainder of 150.
Record the quotient 5 as the next digit in the result. 
Result so far: 31831.5
If we subtract 2180 from 2330, we get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Let's proceed to step 10:
If we divide 1500 by 436, we get 3 and a remainder of 192.
Write down 3 as next digit of the result. 
Result so far: 31831.53
Subtract 1308 from 1500 to get 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Advancing to step 11:
1920 divided by 436 is 4 with a remainder of 176.
Put 4 as the next digit of the answer. 
Result so far: 31831.534
If we subtract 1744 from 1920, we get 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

On to step 12:
436 can be fit into 1760 4 times, resulting in a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 31831.5344
Subtract 1744 from 1760 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Our division results in 31831.5344 with a remaining 0.00016.
